| | | 2,4-Dichlorobenzoic acid Usage And Synthesis |
| Chemical Properties | white powder | | Uses | 2,4-Dichlorobenzoic Acid is a di-halogenated benzoic acid
derivative and an intermediate in the synthesis of spirodiclofen
(S682990), a tetronic acid acaricide fungicide used in controlling
red mites. | | Uses | 2,4-Dichlorobenzoic acid is used as reagent during the synthesis of
pyrimido[2?,1?:2,3]thiazolo[4,5-b]quinoxaline derivatives. It is
also used as starting reagent during the synthesis of
1-(substituted)-1,4-dihydro-6-nitro-4-oxo-7-(sub-secondary
amino)-quinoline-3-carboxylic acids. | | Definition | ChEBI: A chlorobenzoic acid that is benzoic acid in which the ring
hydrogens at positions 2 and 4 are substituted by chloro groups. | | General Description | White to slightly yellowish powder. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | 2,4-Dichlorobenzoic acid is a halogenated carboxylic acid.
Carboxylic acids donate hydrogen ions if a base is present to
accept them. They react in this way with all bases, both organic
(for example, the amines) and inorganic. Their reactions with
bases, called "neutralizations", are accompanied by the evolution
of substantial amounts of heat. Neutralization between an acid and
a base produces water plus a salt. Carboxylic acids with six or
fewer carbon atoms are freely or moderately soluble in water; those
with more than six carbons are slightly soluble in water. Soluble
carboxylic acid dissociate to an extent in water to yield hydrogen
ions. The pH of solutions of carboxylic acids is therefore less
than 7.0. Many insoluble carboxylic acids react rapidly with
aqueous solutions containing a chemical base and dissolve as the
neutralization generates a soluble salt. Carboxylic acids in
aqueous solution and liquid or molten carboxylic acids can react
with active metals to form gaseous hydrogen and a metal salt. Such
reactions occur in principle for solid carboxylic acids as well,
but are slow if the solid acid remains dry. Even "insoluble"
carboxylic acids may absorb enough water from the air and dissolve
sufficiently in 2,4-Dichlorobenzoic acid to corrode or dissolve
iron, steel, and aluminum parts and containers. Carboxylic acids,
like other acids, react with cyanide salts to generate gaseous
hydrogen cyanide. The reaction is slower for dry, solid carboxylic
acids. Insoluble carboxylic acids react with solutions of cyanides
to cause the release of gaseous hydrogen cyanide. Flammable and/or
toxic gases and heat are generated by the reaction of carboxylic
acids with diazo compounds, dithiocarbamates, isocyanates,
mercaptans, nitrides, and sulfides. Carboxylic acids, especially in
aqueous solution, also react with sulfites, nitrites, thiosulfates
(to give H2S and SO3), dithionites (SO2), to generate flammable
and/or toxic gases and heat. Their reaction with carbonates and
bicarbonates generates a harmless gas (carbon dioxide) but still
heat. Like other organic compounds, carboxylic acids can be
oxidized by strong oxidizing agents and reduced by strong reducing
agents. These reactions generate heat. A wide variety of products
is possible. Like other acids, carboxylic acids may initiate
polymerization reactions; like other acids, they often catalyze
(increase the rate of) chemical reactions. | | Fire Hazard | Flash point data for 2,4-Dichlorobenzoic acid are not available;
however, 2,4-Dichlorobenzoic acid is probably combustible. |
